A precision locking pin or mechanism used in chucks and clamping systems to secure workpieces during machining operations.

技术定义与适配语境
典型 锁紧销/锁紧机构 会按材料、尺寸公差、适配关系和失效风险在 机械和设备制造 中评估。

A mechanical component designed to engage with mating features on a chuck or locking mechanism to prevent rotational or axial movement of workpieces during machining processes. It typically consists of a hardened steel pin with precise geometry that interfaces with corresponding grooves or holes, often incorporating spring-loaded or hydraulic actuation for reliable engagement and disengagement.

定义
A mechanical component designed to engage with mating features on a chuck or locking mechanism to prevent rotational or axial movement of workpieces during machining processes. It typically consists of a hardened steel pin with precise geometry that interfaces with corresponding grooves or holes, often incorporating spring-loaded or hydraulic actuation for reliable engagement and disengagement.
工作原理
The locking pin operates by mechanical interference or positive engagement. When activated (manually, pneumatically, or hydraulically), the pin extends into a precisely machined recess or groove on the rotating component, creating a rigid connection that prevents relative motion. Disengagement retracts the pin, allowing free rotation or removal of the workpiece. Some advanced versions use tapered or ball-lock designs for self-centering and increased holding force.
材料
Typically made from alloy steels (AISI 41404340) or tool steels (D2A2) with hardness 45-60 HRC. Corrosion-resistant variants use stainless steels (17-4PH316). Surface treatments include nitridingchrome platingor TiN coating for wear resistance.

常见问题

What maintenance is required for locking pins?

Regular inspection for wear, lubrication of moving parts, and verification of engagement force. Replace if wear exceeds 0.1mm or if engagement becomes inconsistent.

Can locking pins be customized for specific applications?

Yes, custom diameters, lengths, materials, and actuation methods (manual, pneumatic, hydraulic) are available to match specific chuck designs and operational requirements.
